Programming your 363LM

Setup depends on the exact receiver and hardware revision. These model notes do not establish a complete pairing sequence for your equipment.

Match both the remote and opener or external receiver. Keep the door or gate in sight and clear of people. Do not hold a LEARN button or erase memory unless the instructions for that exact equipment require it.

Compatibility & exclusions

315 MHz fixed code, not Security+ rolling code; verify actual receiver.

Replacement equivalence and receiver-specific commercial/gate enrollment remain unverified unless separately documented.
